Summary
The temperature dependence of tensile creep of butadiene rubber (BR) loaded with different concentrations of carbon black ISAF was tested under different applied stresses. The steady creep rate showed a dependence on stress, temperature and carbon black content. The energy-activating steady creep was of order 0.15 eV for samples containing 20 phr of ISAF carbon black and reached a value of 0.37 eV for samples containing 80 phr of carbon black. This was attributed to the blocking of motion of the molecular segments by the carbon black. This view point was confirmed by the activation volume which was found to decrease with the increase of carbon black content.
The stress sensitivity parameter was found decrease from 3.4 for samples containing 20 phr to 1.8 for samples containing 80 phr of carbon black.
